To all whom it may concern:

Be it known that I, WAYNE E. SIMoNs, a citizen of the United States, anda resident of Boyd, in the county of Wasco and State ofl Oregon, haveinvented certain new and useful Improvements in Tractors, of which thefollowing isa specification.

My invention is an improvement in tractors, and has for its object toprovide a device of the character specied especially designed fordrawing farm machines in hilly and soft ground and in hill side work,and wherein the transmission is inclosed to protect it from dirt and thelike.

In the drawings: al Figure 1 is a side view of the improved tractor withparts broken away,

Fig. 2 is a top plan view, and Fig. 3 is a horizontal section. v In thepresent embodiment of the .invention, a suitable supporting frame isprovided, the said frame consistin of side members 1 which converge at teir front ends as shown, and are connected at their l rear end by crossbars 2.

At the converging front ends a yoke 4 is journaled, and a front wheel 5is arranged The body of this yoke has rigid therewith and above theframe a gear segment 6.

A steering wheel 7 is secured to a steering shaft 8 which is journaledin suitable supports on the frame, and this shaft has a front section 9which is provided with a beveled gear 10 meshin with the gear segment 6,the section 9 eing connected to the section 8 by means of a universaljoint 11. The shaft section 9 is supported in a bearing 12 on the frame.

A rear axle 13 is journaled transversely of the frame, and wheels 14 arearranged on the ends of the axle. One of the wheels 14 is rigidlysecured to the' axle, and the other is. revolubly mounted thereon and isadapted to be connected to the axle by'a clutch mechp anism indicated at15 in Fig. 3. A gear or transmission casingv 16 is connected to` theframe at the rear axle, the said axle passing through the casing, and agear wheel 17 is keyed to the axle within the gear casing.

This gear wheel 17 lmeshes with a pinion 18 keyed to a counter-shaft 19also journaled in the gear casin in front of the axle,

` and the said counter-s aft carries two gear the clutch element pinion22 is slidable thereover, 'being merely a gear ring, having an externalseries of teeth adapted to meshvwith the gear wheel 19.

The engagement of the gear Wheels 19 and 22 provides low speed, and theengagement of the gear wheels 20 and 24 provides high `speed, and theengagement of the .gear

wheels 19 and l23 25, a reverse.

This idler 25 is journaled on a slidev 26 which is movable through aguide 27 in the gear casing 16 into and out of mesh with the gears 19and 23. A gear wheel 28 is keyed to the shaft 21 outside of the gearcasing, and this gear wheel meshes with a pinion 29 on the shaft 30 ofan internal combustion engine indicated at 31 and of usual construction.

' A belt wheel or pulley 32 is journaled loosely on the motor shaft andby means of a vbelt 33 the pulley may be connected to machinery to bedriven, as for instance, a threshing machine. The loose ground wheel hasa clutch face on the inner end of the'hub and the movable portion of theclutch 15 which is a grooved collar splined on the axle provides throughan idler has a 'clutch face adapted to coperate with on the hub of theground wheel v i The movable portion of the clutch 15 is controlled by alever 34 which is pivoted to the frame, and has latch mechanismforcooperating with a toothed quadrant for holding it in adjustedposition. connected by a link 35 with. toggle levers 36,

one o f which is pivoted to the gear casing at itsl outer end, and theother is pivoted to a yoke 37 which is pivoted to a bracket 37aextending 'outwardly from the frame forwardly of the axle and whichoperates the clutch the yoke engaging within the groove of themovable-member of the clutch. This lever 34 and the steering wheel 7 arear- The lever VisA Y ranged adjacent to the seat 38, so that the driverin the seat may control both the lever and the Wheel.

Upon the shaft 8 is slidably mounted a link or rod 39 Which controls thethrottle 40 of the engine.V This link or rod is normally movable in onedirection by a coil spring 41, and it has a hook adjacent to thesteering Wheel for convenience in operating the link.

Referring to Figs. 1 and 2, it Will be noticed that the Wheel 5 has acontinuous radial rib 42 at the center of its peripheral surface forpreventing side slipping, and the Wheels 14 have transverse cleats 43for increasing traction. In order to prevent upset in hill side workwhen turning to the right, the right Wheel 14 of the tractor has anextension 44, the said extension consisting of a rim registering withthe rim of the Wheel, and provided With cleats which register With thecleats of the wheel, and the lsaid extension increases the engagingsurface of the Wheel approximately 50%, be-

For the low speed, he Will engage the' gear 23 With the gear 19. For thehigh speed, he will engage the gear 24 with the gear 20, and for thereverse he Will engage the gear 25 with the gears 19 and 23. Anysuitable mechanism may be provided for operating the gears of thetransmission.

The right Wheel 14 is at all times rigid with the axle, the left wheelbeing arranged to be released during turning, thus permit ting adifferential connection between thel Wheels to be dispensed vvith. Thisis an advantage in side hill Work, since most ot' the weight will be onone drive Wheel, While the differential lgear gives power equal to bothWheels.

I claim In a tractor, a supporting frame, an axle journaled therein,means for driving the axle, a ground wheel rigidly secured on one end ofthe axle, a ground wheel revolubly mounted on the other end of the axle,a clutch element on the inner end of the hub of the loose wheel, agrooved collar splined upon the axle and having a clutch face engageablewith said clutch element, a bracket extending outwardly from said frameforwardly of the axle, a yoke pivoted upon said bracket, engaging Withinsaid groove and extending rearwardly beyond the axle, a link pivoted atone end upon the frame near the longitudinal center thereof andextending in a rearwardly inclined direction, a second link pivoted uponthe rear end of the yoke and pivotally connected With the rear end ofsaid first named link, a lever pivoted upon the frame lfor movement in avertical plane, a link connected with the lever and with the pivotalconnection of said links, and means for holding said lever in selectedpositions.
